Anaerobic biological model implementation in CFD tool

Traditionally, anaerobic digestion has been used for the reduction of volatile suspended solids and mass of concentrated sludge produced in Waste Water Treatment Plants (WWTPs). In recent years, anaerobic biological treatment has been widely introduced due to biogas production and low energy cost. Furthermore, it has been extended to waste water treatment and other waste streams (e.g. agriculture and livestock waste) as different configurations such as Upflow Anaerobic Sludge Blanket (UASB) or Anaerobic Membrane Bioreactor (AnMBR). Nevertheless, there are some important factors to control in anaerobic treatment such as temperature, pH and inhibitory compounds so that the operation of these processes are not as robust as Conventional Activated Sludge (CAS).
